Most change order fights aren't about the work. They're about a missing price, a missing "not included," or no paper at all. The fix is a short form you fill in every time and a habit of getting it approved before anyone picks up a tool.
01Why verbal change orders cost you money
You're framing the basement and the homeowner walks down: "While you're here, can you add an outlet by the bar?" You say sure. It's a couple of hours with the box, the wire and maybe an inspection callback. Nobody writes anything down.
Months later the final invoice says "extra outlet" and the client says, "I thought that was included." Now you eat it, or you argue with someone you were hoping would leave you a good review.
Contractors talk about this all the time. In one r/GeneralContractor thread, a contractor said they'd lost money on almost every verbal change order they'd agreed to. The fix that keeps coming up is simple: get written approval before the work starts, even if it's just a text with a photo and a price.
Where the money leaks
| Leak | What happens |
|---|---|
| Never billed | The change happened, nobody wrote it down, and it never made it onto an invoice. |
| Billed late, disputed | It shows up for the first time on the final invoice. The client doesn't remember a price, or thought it was free. |
| Underpriced on the spot | You quoted a number in the hallway and forgot the trip, the sub, the permit, the disposal and the schedule hit. |
| Schedule hit not agreed | The change added days, but the client still expects the original finish date. Now you're "late." |
| Crew or sub said yes | Your lead carpenter or the electrician agreed to something on site that you never heard about. |

Work on this change begins only after written approval. All other terms of the original agreement stay the same. This change order becomes part of the agreement when signed or approved in writing by both parties.

Get the clause and the text script that go with it
The template is the paper. The free PDF covers the two things that make clients actually sign it: a sample "changes to the work" contract clause to take to your attorney, and the "let me write it up" script for clients, crew and subs, plus the approval text you can save as a phone shortcut.
03How to fill it in so it holds up
- Specific scope. "Add outlet" invites an argument. "Add one 20A duplex outlet on the bar wall, about 4 ft left of the refrigerator, standard counter height, white device and plate to match" doesn't.
- Who asked for it. Client, designer, hidden condition or inspector. It matters later if anyone asks why the price went up.
- "Not included," every time. That's where most "I thought that was included" fights come from.
- The running total. Original contract + prior changes + this change = new total. Nobody should be surprised by the sum at the end.
- Days, even if zero. "No change to completion date" is a sentence worth writing.
- A decision deadline when timing matters. "Approve by Wednesday 5 PM, before drywall Thursday. After drywall it needs a cut-in and patch, priced separately." It's honest, and you get faster answers.
- One change per change order. Bundle five changes and one disagreement holds up all five.
- Numbered and logged. The CO number on the form, in your log, on the approval reply and on the invoice line should all match.

04How to get clients to sign before work starts
A good form doesn't help if it shows up a week after the work. Getting a signature first comes down to four things: set the rule at the start, have the words ready, make approving easy, and hold the line on small stuff.
1. Set the rule before the job starts
At contract signing, say it out loud: "Any change, even a small one, gets a written change order with the price and the days before we build it. You'll get a text, you reply to approve, and it goes on the next invoice as its own line." When the rule shows up later, it's one they already agreed to, not something you made up mid-job.
2. Have the words ready on site
3. Make approving take ten seconds
Put the price and the days in the message itself, so the client knows what they're saying yes to without opening an attachment:
Save it as a text replacement on your phone (iPhone: Settings → General → Keyboard → Text Replacement; on Android, check your keyboard's personal dictionary or shortcuts) so it's two taps on site. Whether a text reply counts as written approval depends on your state and your contract. If your attorney says it doesn't, send the same message with an e-signature link, or have the client sign on your tablet.
4. Hold the line, then bill it right away
- No paper, no work. If there's no approval, the change waits. Say it nicely and stick to it.
- Small ones count. Small changes add up, and skipping them teaches the client that changes are free.
- Bill it on the next invoice or draw. As its own line with the CO number: "CO-KIT-03: Add 20A outlet at bar wall." Not buried in "misc." Not saved for the final bill.
- Truly urgent? For a safety hazard or active water damage, do only what's needed to make it safe and send the change order the same day. Your contract should cover this.
05Back it up in your contract
The form and the script work best when your contract already says changes have to be in writing. A typical "changes to the work" section covers:
- Written change orders required for any change to scope, materials, finishes, schedule or price, approved before the changed work starts.
- No verbal changes. Requests or approvals made to employees or subs on site don't count until they're on an approved change order. Name who can agree to changes for your company.
- How approval works: signature, e-signature, or a written reply from the client's listed phone or email that names the CO number.
- Pricing: fixed price, or time and materials at stated rates and markups, with a minimum charge per change order and a rule for credits on deleted work.
- Schedule: the completion date moves by the days on each approved change order, including delays while waiting on the owner's decision.
- Urgent and hidden conditions: what you can do right away to make things safe, and how quickly you'll notify the owner.

06Make it fast enough to do every time
The real reason change orders get skipped: typing one up on your phone takes longer than the work itself. If writing it up takes two minutes, you'll do it. If it takes twenty, you won't.
Here's a phone-only way to get it down to a few minutes with ChatGPT or Claude:
- Capture it on site. Talk the change into your phone: what, where, hours, materials, any sub cost, the deadline. For example: "Kitchen job. Client wants extra outlet on bar wall, 20A, about 4 ft left of fridge. 2 hrs labor, $40 parts. Needs to be done before drywall Thursday."
- Let the AI draft it. Paste the note in with instructions to fill your template: scope, not included, cost table, days added and an approval line. Tell it to use only your numbers and to write NEEDS PRICE if one is missing.
- Review it like the client will. Check the numbers, the scope and the days. You set the price. The AI only writes the words.
- Send, log, bill. Text it with the approval message above, log it as Sent, and put it on the next invoice once it's approved.
Two cautions: never send AI output without reading it, and leave gate codes, alarm codes and payment details out of anything you paste in.

07FAQ
Is a text reply "APPROVED" good enough?
It depends on your state and your contract. Some places have specific rules for home improvement change orders. Ask a local construction attorney, have your contract spell out how approval works, and use e-signature if you're unsure.
Do I need a change order for small changes?
Yes. Small ones are the ones that get forgotten, and they add up. A short change order with a price and "no change to completion date" takes a couple of minutes and keeps the expectation clear.
What if the client won't sign?
Then the change waits, and you build what's in the contract. Be friendly about it: "No problem. We'll stick with the original plan unless you want to approve this one." If timing matters, say so plainly with a decision deadline.
I use Buildertrend or JobTread. Do I still need this?
Keep your PM software as the system of record and use its change order and approval features. The checklist and the script still apply. They're what gets the change into the software before the work starts.
Does a change order replace my contract?
No. It adds to it. Your contract should say changes require a written change order, and every change order should say the rest of the agreement stays the same.
